However,polyacrylamide emulsion synthesized by dispersion polymerization method has several advantagessuchasfastdissolutionspeed,convenienceoffieldapplicationandenvironmentallyfriendly. Thisemul鄄 sion can be fully dissolved at normal temperature within 15鄄20 minutes. Preliminary study on profile modification technique in offshore oilfield is developed with production characteristics on offshore. The study shows that,this system can be directly allocated with injected seawater of Shengli Chengdao Oilfield and can fast di
